For limited company directors in the UK earning over £100,000, determining the optimal salary and dividend combination is essential to minimise tax liabilities. A tax optimiser identifies the most tax-efficient split by factoring in the personal allowance, higher rate threshold, and National Insurance Contributions (NICs). For 2025/26, the personal allowance stands at £12,570 and the higher rate threshold at £50,270—both critical figures for this calculation.
Understanding the Tax Implications of Salaries and Dividends
Salaries are subject to income tax and National Insurance Contributions, just like regular employment income. The 2025/26 tax year applies rates of 20% for basic rate taxpayers, 40% for higher rate taxpayers, and 45% for additional rate taxpayers. Dividends, by contrast, are taxed at 32.5% for higher rate taxpayers and 38.1% for additional rate taxpayers, with a £500 dividend allowance reducing the initial tax burden. Adjusting your salary and dividend split can significantly lower your overall tax liability when approached strategically.
Salary Sacrifice and Pension Contributions
Pension contributions reduce your taxable income, lowering both income tax and National Insurance liabilities. For 2025/26, the annual allowance is £60,000, though high earners may face tapering. Salary sacrifice schemes offer another route to make pension contributions efficiently, provided they're structured correctly to ensure tax compliance and maximum benefit.
Using a Tax Optimiser to Calculate the Optimal Split
A tax optimiser tailors calculations to your specific circumstances, including earnings, tax rates, and pension contributions. For instance, a director earning £120,000 annually may discover that a £30,000 salary and £90,000 dividend combination yields greater tax efficiency than £50,000 salary and £70,000 dividends. The tool provides clarity on potential savings and the most effective approach for your situation.
Case Study: Tax Optimiser in Action
A director earning £150,000 annually uses a tax optimiser to compare strategies. Taking a £25,000 salary and £125,000 dividend split generates £5,500 in tax savings versus a £40,000 salary and £110,000 dividend arrangement. This demonstrates the real-world impact of optimised planning.
